Elderly Physical Activity Program Retention Factors in Aracaju, Brazil

An observational study of 526 older adults (477 females, mean age 66.4 years) in Aracaju, Brazil, analyzing length of stay in a Community Physical Activity Program. Cristiane Kelly Aquino dos Santos authored the research, which used Kaplan-Meier survival analysis and Cox regression to identify associated factors. The study found a 58.1% stay rate after three months, with only 1% of subjects remaining until the cohort's end.

Use Cases

• Predicting participant dropout risk in community health programs based on demographic and health factors mentioned in the description
• Modeling survival curves for program retention based on the Kaplan-Meier analysis described
• Identifying factors associated with program adherence based on variables like sex and osteoporosis diagnosis status
• Benchmarking retention rates for similar physical activity interventions using the reported 58.1% three-month stay rate

Strengths

• Sample size of 526 older adults provides a basis for statistical analysis
• Includes specific metrics like a 58.1% stay rate after three months and a 1% retention rate until cohort end
• Analysis used established statistical methods (Kaplan-Meier estimator, Cox regression) as described

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download
• Data may reflect geographic bias inherent to the single-city (Aracaju) study design
• Last update date is unknown; freshness unverified
